MAVCHINEFOR MAKING PAPER HOOPS.

SPECIFICATION forming part of Letters Patent No. 505,421, dated September 19, 1893. Application iiled January 11, 1893. Serial No. 458.042. (No model.)

To aZZ whom it may concern: V-shaped cross section and V shaped cutting Be it known that I, WALTER E. FROST, a ends or edges. The cutting ends of these citizen of the United States, residing at Lewisknives rest in an inverted position on the bed ton, in the county of Androscoggin and State roll B, the edges of the knives resting in an- 5 of Maine, have invented certain new and usenular grooves formed in the roll for this pnr- 55 ful Improvements in Machines for Making pose. The lower cutting edge of the knife is Paper Hoops; and I do hereby declare the folthus brought below the general surface of the lowing to be a full, clear, and exact descriproll and a clean cut is assured. The size and tion ot' the invention, such as will enable othspacing ofthe knives are such that the cut secro ers skilled in the art to which it appertains to tion included between the two edges of one 6o make and use the saine. knife will be equal to the section between the My invention relates to a machine for cntadjacent edges of two adjacent knives, so that ting beveled hoops from sheets of paper or the sheet will be cut into strips of equal secother like material and for pressing said hoops tion and without any waste. The feed rolls 15 after they have been cut from the sheet. The C rest on the bed roll between the knives. 65 hoops which I design to make on my machine The rear end of each knife is secured to a stem are to be used on orange boxes, barrels, dac., e which is held by a set screw g in an openand they are to be cut 'from leather board or ing in a collar Gr the collar being in turn. sesome other strong material having tensile cured to a shaft F by means of a set screw g.

The cutting beveled strips Without waste of material and 5o is accomplished by means of knives e having that the strips are then carried alternately to roo the upper and under rolls where they are pressed and rounded 0E to form the pressed hoops which I aim to produce by the use of my machine. The hoops thus produced are adapted to be used on boxes, barrels and the like and are found to be superior to wood for the reason that they will not break when bent around a sharp corner.

I am aware that machines for cutting paper have been used containing a series of feed rolls with upright cutting knives between them each strip as out being drawn through by a pair of rolls. In my machine I dispense with every alternate pair of rolls by making my knife V shaped as described, the strip which passes between the two parts of the knife being fed or drawn along by the uncut portion of the sheet. Again, my knives being once in adjustment require no further adjustment as the space between the two edges of the knife and between the grooves remains constant.

I claim- In a machine for cutting hoops from sheets of lpaper or other like material, the combination of a bed roll having annular grooves therein, knives having, when in position an inverted V-shaped cross section and end cutting edges, the lower edges of said knives resting at their forward ends in said grooves and feed rolls between said knives, substantially as described. i

In testimony whereof I affix my signature in presence of two witnesses.
